Inspection of electronic cigarettes in China


Sometimes an importer asks me what the “hot products” are at the moment.

Well, one really obvious response is electronic cigarettes. New factories making e-cigarettes pop up every month in Shenzhen.

Several people already asked me how to check this product. So here is a generic checklist that we use:

General Inspection

Look for scratches, dirt and marks on the item. Look for loose or missing parts, sharp protrusions, cracks, dents. Check basic function.

Count every defect in the defect list

Item Weight

Check weight of item.

Conforms to specs

Function Test

Use item as normally intended. Check all functions and features in the manual.

Functions as intended

Extended Function Check

Run item for 4 hours.

Functions as intended

Rub Test

Rub the markings and the logo 20 times, with a soft cloth dipped in alcohol (if no alcohol is available, use oxygen water and mention it in the findings).

The markings should stay the same.

Coating Adhesion

Apply and remove 3M tape to paint, coatings and logos. Check for damage.

No damage or discoloration.

Assembly Check

Assemble per instructions.

Easy to assemble, no missing pieces

Smell Test

Check for unusual odor while item is on and after it is turned off.

No unusual odor

Battery Check

Check battery fitness, marking and rating voltage. Check production date and expiration date.

Conforms to specs

Battery Charge

Use fully depleted battery and charge. Insert battery into item to test. Run until battery is fully drained. Record time.

Fully charged, item functions.

Stop Test

Use item and then stop.

Function stops right away

Accessories Check

Connect any accessories that are compatible with item and check their function (PCC, USB charger, etc).

Functions as intended

Fatigue Test

Connect and disconnect charger, cartridge and other adjustable parts 50 times.

No loss of function

Good fit, case operates well
